badri住宅位于印度班加罗尔,是一处典型的位于紧凑型城市地块上的房屋,建筑面积为511 m2。业主希望设计师可以将住宅分为两种空间,一部分为私人空间,另一部分用于与家人朋友日常交流,以此鼓励互动和情感融合。最终的设计方案将建筑内外的设计抽象并概念化为一系列寻求"愉悦感"的情节与元素。有着双倍层高的二层起居室空间是整个建筑的灵魂,它将客厅、餐厅、厨房、祈祷室以及室外平台串联成一个整体。同时其内部自带的阳台,更进一步赋予这个空间以盎然生机。流动的空间在满足了个人需求的同时,也营造了舒适而温馨的公共功能区域,为家庭提供了互动空间。在该空间中,设计师不拘一格地使用装饰材料,并加入丰富的色彩和肌理,令空间充满温暖和喜悦。

对不同灌溉处理下水、旱稻根系生长及水分利用效率的研究结果表明:不同灌溉处理对旱稻根系的垂直分布深度无多大区别,基本上多在0～60cm间,灌水越多分布在表层（0～30cm）的根系越多,分布在深层（30～60cm）的根系越少。但不同水分处理... 详细信息

对不同灌溉处理下水、旱稻根系生长及水分利用效率的研究结果表明:不同灌溉处理对旱稻根系的垂直分布深度无多大区别,基本上多在0～60cm间,灌水越多分布在表层（0～30cm）的根系越多,分布在深层（30～60cm）的根系越少。但不同水分处理对早稻297的反应不同,充分灌水处理形成了较大的根系系统,总根量大于干旱胁迫处理,但其上层根系占的百分率最高;干旱胁迫条件下形成的根系系统中下层土壤中根系占的百分率要高。对于津稻305,与旱稻297相比,各处理总根重都有所减少,大部分根都集中在表层。旱稻297的水分利用效率高于津稻305,而且两品种灌溉水的水分利用效率都比（灌溉+降水）的水分利用效率高。

Experimental Investigation and modelling for the Optimisation of Conduction Cooled HTS Hybrid Current Leads for SmES

In the lithography section of the ITRS 2006 update, at the top of the list of difficult challenges appears the text "overlay of multiple exposures including mask image placement". This is a reflection of the fact that today overlay is becoming a major yield risk factor in semiconductor manufacturing. Historically, lithographers have achieved sufficient alignment accuracy and hence layer to layer overlay control by relying on models which define overlay as a linear function of the field and wafer coordinates. These linear terms were easily translated to correctibles in the available exposure tool degrees of freedom on the wafer and reticle stages. However, as the 45 nm half pitch node reaches production, exposure tool vendors have begun to make available, and lithographers have begun to utilize so called high order wafer and field control, in which either look up table or high order polynomial models are modified on a product by product basis. In this paper, the major challenges of this transition will be described. It will include characterization of the sources of variation which need to be controlled by these new models and the overlay and alignment sampling optimization problem which needs to be addressed, while maintaining the ever tightening demands on productivity and cost of ownership.

It′s important that HTS tapes have lower thermal conductivity and higher transversal resistivity in order to reduce the heat leaks conducted along the tapes and AC losses in the high temperature superconducting system conduction cooled by Gm coolers. This paper presents an experimental investigation into the effects of pure Ag and AgAu alloys sheath materials on the properties of bi(2223) multifilamentary tapes and the optimisation of conduction cooled hybrid current leads made from copper and bi(2223)/Ag or bi(2223)/AgAu tapes. The thermal conductivity of the tapes were measured by cryogenic steady heat flux method and the resistance was measured by using standard DC four probe method at low temperature. The results showed that the reduction of thermal conductivity by the addition of Au into the sheath material of bi(2223) tapes was 65 0 0, 75 0 0 and 85 0 0 lower than that of pure Ag sheathed bi(2223) tapes and the increase of resistivity was 4.9 , 10 and 19.4 times higher than that of pure Ag for the addition of 2.2 0 0, 5.7 0 0 and 10.7 0 0Au(atom ratio) respectively. And the study also attempts to optimise thermodynamically the conduction cooled hybrid current lead by using a developed model, which took the irreversibility of commercial Gm coolers, the contact resistance and thermal conductance into account. Predictions from the model showed that AgAu alloys were suitable candidate materials to replace Ag as sheath material of bi(2223) tapes applied in HTS current leads. In addition, bi(2223)/AgAu was a suitable material to be applied as the HTS section of hybrid current leads in conduction cooled superconducting electric systems.
